Opponents of the recently adopted plastic bag tax in Seattle haven't given up the fight. According to this Seattle Post Intelligencer story, a trade group representing independent grocery stores is trying to gather enough signatures to put the issue to a voters' referendum this fall.

The group started mobilizing grocers and volunteers to areas around the city last Friday to gather signatures -- they'll need to have accumulated 14,374 legitimate signatures by Aug. 28 for the petition to make it on to the ballot.

"We think taxing family grocery bills is a really bad idea," said Jan Gee, president and CEO of the Washington Food Industry. "Food prices are so high right now, and price increases keep going up -- they're really out of the control of grocers."
